Summary:
After updating the jenkins test workers, chrome and python changes resulting in a scattering of test failures.
* Clicking on an icon that has been transformed to mirror around the y axis fails via selenium. Not sure why. "Fixed" by asking the browser to do the click.
* There was a small change from python 3.9.6 to python 3.9.7 that affected completion of property attributes.
